Question 962829
Could you please help solve this quadratic equation using completing the square method? 
x^2+9x+8=0
complete the square: (take 1/2 the coefficient of the x-term(9/2) and square it)
(x^2+9x+81/4)-81/4+8=0
(x+9/2)^2=81/4-32/4=49/4
(x+9/2)^2=49/4
take sqrt of both sides
x+9/2=±√(49/4)
x=-9/2±7/2
x=-16/2=-8
or
x=-2/2=-1
